Patented June 13, 1933 "UNITED STATES PATENT OFFICE WILLARD T. MUNSON, OF SCH/ANTON, PENNSYLVANIA, ASSIGNOR T0 COLLINS SUPPLY AND EQUIPMENT COMPANY, OF SOB-ANTON, PENNSYLVANIA I i on. GUARD r012. SPINNING RINGS Application filed A u g ust 11, 1932. Serial N0. 628,433.

This .invention relates to spinning rings and their holders and has special reference to an oil splash guard for such rings and holders.

One of the problems which silk mill owners have had to meet has been to protect the silk in spinning machines from splashing of the oil onto the silk from the traveller as it picks up the lubricant which is applied to the ring. Various devices have been tried out to provide protection for the bobbins from this oil but none of these devices hitherto used have proven satisfactory since most of them require either to be fixed permanently to the ring rail or to be secured by the screws which hold the ring holder in position so that they cannot readily be removed for cleansing.

One important object of the invention is to provide an improved oil guard for this purpose adapted to be readily attached to a ring holder having upstanding flange portions to support the ring.

A second important object of the invention is to provide an improved arrangement of this kind wherein the guard is held in position on the ring holder by the ring itself.

A third important object of the invention is to provide an improved oil guard for this purpose wherein the guard is mounted in such manner that lifting the ringfrom its holder permits free lifting of the guard from the holder.

A fourth important object of the invention is to provide an improved form of oil guard especially adapted for use in connection with the ring and holder disclosed in the patent to B. L. Bloom, No. 1,663,620.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing and specifically claimed.

In the accompanying drawing like characters of reference indicate like parts in the several views, and:

Figure 1 is a plan view of the holder, ring and oil guard assembled.

Figure 2 is asection on the line 22 of T A F igurel.

Figure 3 is an enlarged detail section on the line 33 of Figure 1-.

Figure 4 is a detail section on the line 44 tion'is' cut with an inverted U-shaped slit to form a lug 13 which is pressed inwardly to extend upwardly on the inner side of the respective portion 12 and'thus form a ring seat as can be clearly seen in Figure 3. l

The ring itself has the usual annular body depending bead 15 at its innerperiphery beneath which the feet of the traveller engage, this bead being spaced from theflange 11 when the parts are assembled. A verti cal flange 16 depends from the outer periphery of the ring body 14: and rests on top of the lugs 13, fitting tightly between the upstanding flange portions 12 so that the ring is held securely in place by this frictional .70 1 1 dished inwardly and provided with a I engagement with its holder but may be readily lifted out of the holder without the use of tools. g

The oil guard consists of an upstanding 'arcuate strip 17 of thin sheet metal extending around the outer periphery of the ring and holder somewhat more than 180'degrees. This guard rests at its lower part against the outer faces of certain of the flange portions 12andop'posite each of the portions .12 against which it rests is slitted and bent to provide a spaced pair ofinwardly offset lugs 18 of slightly less height than the lug 13 and so spacedthat the lug 13 fits between "them. I

By reason of this construction, the guard inay'have its lug provided portions slipped over the portions 12 of the holder and then, by placing the ring in the holder, the guard is secured in position. Obviously, the

splashing of oil from the traveller onto the bobbin is absolutely prevented.

There has thus been provided a simpleand efficient device of the kind described and for thepurpose specified.

It is obvious that minor changes may be an oil guard consisting of an arcuate strip of metal extending around the outer periphery of the holder and resting against the outer faces of the flange portions, said guard being provided on its inner face with spaced pairs of lugs arranged to engage over the side edges of said flange portions and spaced to embrace the lugs of said flange portions between them, said guard lugs being of slightly less height than the lugs of the flange portions, and a ring embraced by said flange portions and resting on the lugs thereof over the guard lugs to hold the guard from displacement.

In testimony whereof I affix my signature.

made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. The combination with a spinning ring holder having upstanding spaced peripheral flange portions; of an oil guard consisting of an arcuate strip of metal extending around the outer periphery of the holder and provided with spaced sleeves at its lower edge fitting removably on the spaced flange portions of the holder.

2 The combination with a spinning ring holder having upstanding spaced peripheral flange portions; of an oil guard consisting of an arcuate strip of metal extending around the outer periphery of the holder and provided with spaced sleeves at its lower edge fitting reniovably on the spaced flange portions of the holder, and a ring fitting between the flange portions of the holder over the upper ends of the sleeves to retain the guard in place.

3. The combination with a spinning ring holder having upstanding spaced flange portions on its outer periphery, said flange portions being each provided with a centrally disposed inset lug forming a ring rest; of an oil guard consisting of an arcuate strip of metal extending around the outer periphery of the holder and resting against the outer faces of the flange portions, said guard being provided on its inner face with spaced pairs of lugs arranged to engage over the side edges of said flange portions and spaced to embrace the lugs of said flange portions between them.

4. The combination with a spinning ring holder having upstanding spaced flange portions on its outer periphery, said flange portions being each provided with a centrally disposed inset lug forming a ring rest; of
